Why does my home theater keep turning off?

Imagine watching your favorite movie on the home theater system and suddenly it turns off. In this article, we have explained 6 main reasons that are responsible for this.

Why does my home theater keep turning off? Your home theater system can keep turning off because of issues in the power cord, heating up, power cable, remote control problem, and sleep timer.

Home theater is sometimes a lifesaver from the daily boring routine when you want to watch a movie in an audio environment similar to a theater. This experience can get worse if your home theater starts giving you trouble. It is an audio output device consisting of more than one speaker unit and a subwoofer.

Why does my home theater keep turning off?

There are many reasons that can cause problems in your home theater system. This can be a small issue like a detached power cord or a serious issue like heating up the entire system. Follow this step-by-step guide to keep your system running properly.

A problem in the power outlet

Every power outlet works differently, so identifying a problem in a power outlet will be very different if compared to this process. But it will give you the idea of how you can check your power outlet for issues if it is the reason behind powering off your home theater.

It has a built-in power supply system that does not let the system turn on properly if there are any type of power issues. For example, if the voltages are lower than the supported range, then the system will power off immediately.

To check if your power outlet has an issue, you must get a closer look and listen to it carefully when you are turning on the audio system. Plug the power cord in your power outlet and turn it on. After turning it on, go to your power outlet and observe the outlet very carefully if your outlet is doing any type of sparks.

If your power outlet is doing any type of sparks, then there can be two reasons behind that problem. One reason can be a problem with the power cord; the second reason can be a problem in your socket. If the power cord has thinner pins, then the problem is in the power cord, because it cannot stay in the socket.

If the power cord is fine and still you hear any type of sparking or light noise from the power outlet, then the problem is in the power outlet. This problem can be a bit confusing at first, but there are only two reasons why you can hear these sparks from outside of the power outlet.

The socket might be rusty by being used for a very long time. So, if the conductors are rusty and you are using it for your home appliances like a home speaker system, then they won’t work. If the sockets are not rusty and then you might see blackish color on the copper sockets.

This tells you that the socket is not able to work anymore and you will have to change it.

To resolve the issue in the power socket, you must open the device with proper electrical precautions. If you see any rust on the copper, then remove the rust as much as you can. The best solution for that problem is to replace the power outlet or socket with a new one. It will probably solve the issue.

If your power cord pins are thin and cannot stay in the socket correctly, then get a shoe or a better grip cord and plug it right into the socket to see if the pins fit perfectly in the socket. If the pins fit perfectly, then it will resolve your problem.

The sleep timer is active

Sleep timer has been introduced in electrical appliances for a very long time. Such as on TV, DVD player, home speakers, oven, and many more.

This case can only happen if your home theater system turns off after a specific time, and when you turn it back on, you again see that it automatically turns off after the same time interval. This thoroughly explains that it has a sleep timer running in the background.

Most products have a sleep timer button on the front panel, and most do not have. But they all come with a sleep timer option on the remote controller. You can check the sleep timer quickly by pressing the button on the remote controller. If your audio system has a mini display for configuring minimal settings, then there is no need to turn on the TV for options and stuff.

You can easily change the settings on the mini display. If it does not show settings on the mini display, then you must turn on the display with which the system is connected.

To check if your home audio system has a sleep timer, turn it on and the display device, which is probably a TV. After turning it on, go to the settings and look for general settings. In general settings, you will find a sleep option, if it is on, then turn it off. You can also use a pico projector with this system.

The problem in a remote controller

People will always think that the problem is probably in the hardware, electric socket, or the timer.

No one thinks about the remote controller in this matter, because at an instance you are watching anything on your screen and the next instance it is turned off. This problem also occurs in such a way that you turn it on with a remote or the power button.

When it starts and is ready to take commands from the remote, it suddenly turns off, and you don’t even know what is wrong. The first step you take is to check the power wires are plugged in properly or not.

It happens in such a way that, when you power on the home theater, you might plug a DVD and do not need to use the remote to get our movie or your favorite show started. But when you tend to use your remote to turn down the volume or seek forward or anything else, your movie system turns off immediately.

The problem behind this is that the remote controller of your audio system might be exposed to some moisture, or any liquid or water is being spilled over it. When there is liquid or moisture inside the remote controller, the motherboard does not work correctly. The discussed problem only happens if the remote is sending a turn off signal due to some malfunction in the remote controller.

It is not confirmed that the problem, in this case, can only send the turn off the signal. It can also send the volume or channel switcher signal. It can be anything. What we are trying to explain is that, if the IR sender of your remote controller is in front of the IR receiver, and it turns off by itself. It is probably due to some malfunction in your remote.

This issue can only be resolved by two methods. One of them is you can open up your remote controller and wash the motherboard and full remote with an MBC compound. It will evaporate all the moisture from inside the remote and the motherboard and will remove all dusty or conducting particles that are troubling the remote.

The second thing is that your remote is too old and might have a pressed button in it, which is causing your speakers to turn off frequently. So, if the button map is available separately, then you must replace it. If not, then you must get a new remote controller for your home audio system.

Heating up

It is usually placed in an air-conditioned room because of those who watch movies for cinema-like audio experience watch movies with comfort. So, they are often placed in air-conditioned rooms or halls. You can place the 4k soundbar at a suitable location.

In this way, there is a lesser chance that the home speaker system will burn out or heat up and stop working. It can also get damaged when it is being used for a long time when it is heated up more than its limit.

But some people don’t have an air-conditioned room or separate halls as a movie room. They just keep it in a place where all of their family members can adjust for movie time. These rooms do not have a hot temperature; they almost range from 20 to 28 degrees Celsius.

The problem starts when it is placed into some kind of draw or shelf when it is on.

These are electronic appliances that run on circuit boards and audio video processors. These processors generate heat when they are active and make the environment somehow hotter around them. It also comes with exhaust fans to keep the heat out of them. But still, if it is being used for a very long time, it usually heats up.

If your audio system has an exhaust fan and you place it under covers or shelf, it will probably heat up and it will stop working. If it doesn’t have any exhaust fan, then it will get heated up more quickly than the one with the fan. Because keeping the system in a covered or closed environment is not healthy for it.

The circuit has a trip function, it closes the power or shuts it down properly when detects that the system is heating up. Because of this function, you might see that it is always turning off automatically.

The best way to keep it working is to use it in a cold environment, such as in a room or hall with an air conditioner. If you live in a cool place whose temperature is usually below 20 degrees Celsius, then you can place it anywhere except in a closed environment, such as draw or shelf.

You can keep in on the shelf, but do not put it on the shelf; otherwise, it will heat up and will stop working. But if you live and use it in an environment whose temperature is above 25 degrees Celsius, then you must get an air conditioner to keep the temperature of that area cool enough.

Issue in cables

Cables have a huge role because there are rare cases where home speakers can work without cables. It needs cables to connect with each speaker and subwoofer. The cables that used are sometimes RCA cables, or they are plugged in with the clips directly. These clips hold the wires firmly in their holder to keep it conducting the electric current and keep playing the track or movie.

These are the expensive electronic appliances that must also have a system with which it can save itself from any type of electronic or electric failure. You should properly attach it with a 5.1 home theater system.

You have to manage to fix all the speakers on their required locations, you have to put the audio setup at the center, and you have to pass all wires. You will have to connect them properly to their accurate port so that they do not cause any issue.

It comes with a self-tripping system that is activated only when there is any type of problem. When it is activated, the whole system shuts down by giving an error. This type of error can come by putting the wires in the wrong place.

For example, if the voltage is low, then it will give error and shut down unexpectedly. If the speaker cables are plugged in a wrong port or an incorrect manner, then it will give an error and will shut down. And this will happen more often because you might have set it up in the wrong way.

This usually happens when the cables are not plugged in the right manner if the cables are swapped in the wrong way or have a breakage throughout the cable, it creates looseness in the supply. So, it activates the alarm in the motherboard and turns it off.

The best solution for this problem is that you must get all wires unplugged one by one and check the wire the issue is repeating. The proper way is that, unplug a speaker, and check. If the problem still there, unplug another wire. You must do this process one by one until you find the corresponding cable.

The issue in the head unit

The head unit of a home theater audio system is responsible for controlling the resources for better quality and control. It is the part that is managed by the remote control and function buttons to change the settings and many more.

This head unit is connected to the main motherboard, which has all the resources such as an amplifier, resistors connectors, etc. the head unit is connected with the mainboard using a connecting wire or a conducting attachment such as soldering.

When the soldering is damaged, it is not properly connected to the main motherboard. But is still giving electrical signals and can provide the feed to the motherboard, which then keeps the system working.

If the head unit is connected via a wire, then there is less possibility that the connection between the head unit and the central unit is lost or weak. The main causes for the breakage of this soldering are that the speakers might have a huge jerk to it.

This could happen for many reasons. You might have dropped it from a height, and its internal components have been disturbed by that, but it is still working in this way.

It might be punched by any child so hard that it almost broke the internal components. So, there is no way that you can fix it on your own unless you are a professional electronic expert. There can be another reason for this behavior. Someone might have spilled water or any drink on your audio system.

Spilling water can create a mess and damage it permanently if the system is turned on at that time. But if it is not turned on and it opened and dried before playing, then there is a possibility that it still works but turns off by itself after being turned on for a long time.

These are the possibilities that you can face when your head unit has an issue. If you do not find any issue among the reasons explained before, then there is an internal error that you cannot detect.

It is only detected by an electronic professional; if the head unit is disconnected by any means, then you will need to get the connection back online. If the soldering is excellent and you cannot find any visible problem, then you need to get it checked to the vendor.
